Methods

AcquireStream()

Tries to open the storage stream and lock exclusively for read/write. May throws if the stream is currently acquired elsewhere.

When using file or isolated storage stream, lock the file and use the AcquireSynchronizationLock() for file access synchronization.

Declaration
protected abstract Stream AcquireStream()
Returns
System.IO.Stream

AcquireSynchronizationLock()

Blocks the execution of the current thread until the synchronization lock can be acquired. Returns a System.IDisposable that will release the lock when disposed.

Declaration
protected abstract IDisposable AcquireSynchronizationLock()
Returns
System.IDisposable

Clear()

Clears all entries from the timetable.

Declaration
public void Clear()

Deserialize(Stream)

Deserialize the provided stream to lookup table.

Declaration
protected abstract IDictionary<TKey, DateTime> Deserialize(Stream stream)
Parameters
System.IO.Stream stream

Returns
System.Collections.Generic.IDictionary<TKey, System.DateTime>

Key(TInstance)

Selects only the relevant key information from the instance.

Declaration
protected abstract TKey Key(TInstance instance)
Parameters
TInstance instance

Returns
TKey

Open()

Opens the stream, reads time records, allows debounce checks to be performed, and upon disposal - writes back any new records to the stream.

Declaration
public IDebounceScope<TInstance> Open()
Returns
IDebounceScope<TInstance>

Serialize(Stream, IEnumerable<KeyValuePair<TKey, DateTime>>)

Serialize the lookup table to stream.

Declaration
protected abstract void Serialize(Stream stream, IEnumerable<KeyValuePair<TKey, DateTime>> table)
Parameters
System.IO.Stream stream

System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<TKey, System.DateTime>> table
